platform: generic: Optimize extensions_init() to parse ISA extensions once

2026-06-12T10:38:29Z

Instead of parsing ISA extensions separately for each hart in the generic_extensions_init() function, it is better to parse ISA extensions for all available harts in the cold boot path. Also, this allows us to remove fdt_isa_bitmap from scratch space and directly initialize "extensions" in struct sbi_hart_features for each hart.

platform: generic: Remove platform override hooks

2025-04-23T07:02:51Z

Now that all of the overrides are modifying generic_platform_ops directly, remove the unused hooks and forwarding functions. The remaining members of struct platform_override match struct fdt_driver, so use that type instead. This allows a future commit to reuse the fdt_driver-based init function.

platform: generic: Modify platform ops instead of using hooks

2025-04-23T07:02:51Z

Switch all existing platform overrides to use the helper pattern instead of the platform hooks. After this commit, only the .match_table and .init members of struct platform_override are used. There are two minor behavioral differences: - For Allwinner D1, fdt_add_cpu_idle_states() is now called before the body of generic_final_init(). This should have no functional impact. - For StarFive JH7110, if the /chosen/starfive,boot-hart-id property is missing, the code now falls back to using generic_coldboot_harts, instead of accepting any hart.

platform: generic: Pass FDT to early/final_init overrides

2024-08-24T07:32:54Z

Several of these override functions access the FDT blob. Explicitly indicate which callbacks are allowed to modify the FDT blob by passing the parameter as a possibly-const pointer. This also reduces code size by deduplicating the call to fdt_get_address(). Signed-off-by: Samuel Holland Reviewed-by: Andrew Jones Reviewed-by: Anup Patel
